Tested with Microsoft Edge on Windows 10:
Add some input helpers to the history page.
Zoom to 100 %: Everything looks normal.
Zoom to 75% and refresh the page: Input_text objects still looks ok. So do numeric sensor graphs. Other entities such as input_booleans and input_selects have extended bars that goes outside to the left and thus hiding the entity name. Since the bars extend, the graphs no longer align with the time on the x axis.
